Betta's are egg layers; they don't get pregnant.
She breeds with a male Betta Fish.
Betta fish do not get pregnant Once a female releases her eggs the male fertilises them and places them in a bubble nest that he has made prior to mating
of course not!!!
Male betta fish will build a "bubble nest" when they are getting interested in procreating. Betta fish do not get pregnant they lay their eggs in these nest.
The male fish will take care of the young, once the female lays the eggs then remove the female from the tank or the male betta will injure or kill her. Can a male betta fish get pregnant ? The answer is no.
A betta fish is anywhere from 1 to 2 inches.
Betta fish can be from 2 to 4 inches long when fully grown.
Bettas are egg layers so they do not get pregnant.
Betta Fish can grow to about 4 inches long (about 9cm).
I guess your Betta has a roundish tummy. That is its normal body shape. Bettas certainly can not be pregnant because they are egg layers and don't get pregnant.
